The Avian Infectious Bronchitis Virus (IBV) is highly contagious and frequently mutates, leading to the emergence of new variants.
Current strategies for IBV vaccination and diagnosis
Vaccination, based on classical and/or variant strains, is commonly used to combat this disease.
IBV can be diagnosed using 4 main tools: virus neutralisation, HI test, PCR or ELISA. Each of these tests has its own advantages and limitations
Current limitations encountered
For vaccine monitoring, ELISA remains the tool of choice. However, kit performance may be limited by:
- The evolution of vaccines, and in particular live vaccines, to contain more and more news variants. These variants are not at all, or to a much extent, detected by commercially available kits.
- The difficulty of identifying challenge in vaccinated flock
Our solution: The ID Screen® Infectious Bronchitis Indirect 2.0
Our improved ELISA kit addresses the issues mentioned above:
- By using a very conserved recombinant protein, our kit enables the detection of all existing variants (4/91, 793B, Qx, It02, var02, var206, BR1, Is02…).
- It can be used to identify challenge in vaccinated flocks caused by classical strains or variants.
